Ingredients

Instructions

  1. Step 1: In a small bowl, combine 2 tbsp mayonnaise, 1 tbsp Dijon mustard, 1/4 tsp garlic powder, and 1/8 tsp black pepper. Whisk until smooth to create the mustard aioli.
  2. Step 2: Spread 1 tbsp softened butter evenly on one side of each sourdough bread slice. Heat a skillet over medium heat and toast the bread butter-side down for 2-3 minutes until golden and crisp.
  3. Step 3: Flip the bread slices and quickly spread the mustard aioli on the unbuttered sides. Layer 3 oz thinly sliced smoked ham, 2 oz sharp cheddar cheese, 4 dill pickle slices, and 2 small lettuce leaves on one slice.
  4. Step 4: Top with the other slice of bread, aioli side down, and press gently. Remove from skillet, slice in half, and serve immediately for a nostalgic summer picnic bite.
